Andrew Raingold, Executive Director of the Aldersgate Group, spoke at the launch of the Green Book at the Houses of Parliament. The book proposes innovative new directions for the Liberal Democrats to put the environment at the heart of the economy.

He said: "Nick Clegg is absolutely right to say in the foreword that green policies are of crucial importance to economic recovery and a central component of a stronger economy. Not only is this vital in the short-term, providing 10 per cent of UK GDP, but also in the long-term. Trends in the global economy are moving decisively away from Britain and the book outlines a number of effective proposals for how regulation, taxation and other policy levers could be a pillar of future growth that all political parties should take note of."
